Spot the difference?

I'm convinced that young people today have about the same level of sophistication when it comes to deconstructing advertising as they did 20 years ago. Not because they are less smart, but mainly because they watch TV with one eye and do 4 other things at the same time, and they just don't think about it that much. I want to test classic ads from the 80s and see if they engage young people as much today.

Or perhaps its already happening?
